GEARING FOR OPERATING THE ROLLS FOR MUSIC-SHEETS.

Application filed November 26, 1913.

To all whom it may concern:

Be it known that I, SIDNEY J. STAPLES, a citizen of the United States, residing at l/Vest New York, in the county of Hudson and State of New Jersey, have invented a new and useful Gearing for Operating the Rolls for Music-Sheets, of which the following is a specification.

The object of this invention is to provide a new and improved gearing for operating the rolls for music sheets so that the same can be drawn over the tracker for playing and quickly rewound.

The principal object of the invention is to provide a gearing of this nature which shall be easy to manufacture and efficient in operation.

The gearing is illustrated in the accompanying sheet of drawings in which,

Figure 1 is a front elevation partly in section of the same; Fig. 2 is a rear elevation with the parts in the opposite position from that shown in Fig. 1; Fig. 3 is a sectional plan view taken on the line 33 of Fig. 1; Fig. 4 is a sectional elevation taken on the line 4-4 of Fig. 1; and Fig. 5 is a sectional elevation. on the line 55 of Fig. 1.

Referring to the drawing and in detail, A designates the check or right-hand side of the spool box. Secured to the same by suit-able screws is a bracket 10. A shaft 11 is journaled in the base of the projecting part of said bracket. Said shaft has on its end the usual bushing 12 carrying a springpressed tenon 13 for engagement into the socket or mortise formed in the right-hand end of the music spool B. A sprocket pinion 14 is secured on the end of said shaft projecting beyond the bracket. Secured in the bracket by a nut is a stud or bolt 15 on which is journaled a cam 16 having a projectingarm 17. The cam 16 engages the end of the shaft 11 and the arm 17 is connected to the automatic shifting mechanism in a manner well. understood, so that the cam controls the axial position of the shaft 11 and adjusts the music spool B automatically in proper position so that the music sheet C will run properly on the tracker T. The cam 16 and the arm 17 are connected together by a tie 18, the cam, tie and arm being preferably pressed out of one piece of sheet metal. Another bracket 19 is secured to the cheek A by suitable screws. Journaled in the hub in this bracket Specification of Letters Patent.

fitting into the cheek is a shaft 20 which carries on its end a pinion 21. The shaft 20 is held in place in a bracket 19 by a collar 22 held by a suitable screw on the shaft. A power shaft 23 is journaled in a projecting arm 190 of the bracket 19. The end of the shaft 20 is reduced and fits into a hole in the end of the power shaft so that the two shafts 20 and 23 will come in line and each will be free to turn independently of the other. A collar or hub 24 is secured on the power shaft by a suitable screw. This hub has a projection or clutch tooth 25 arranged in position to engage with a projection or clutch tooth 26 formed on the collar 22. The hub 24 is also provided at its outer end with av clutch tooth 27 set in position to engage clutch tooth 28 formed on a sprocket gear 29 which is loosely mounted on a power shaft 23. The gear 29 has an extending hub 30 provided with a slot in which is fitted an arm 31 secured to the bracket by a screw, whereby the gear 29 will be held in place axially on the power shaft 23.

A sprocket chain 32 is led around the sprocket gear 29 and the sprocket pinion 14. Adjustably secured by means of a nut and screw to the arm 31 is an arm 33 carrying a stud 34 on which is loosely journaled a roller 35 which engages the sprocket chain 32. By adjusting the position of the arm 33 on the arm 31 the wrap of the sprocket chain on the sprocket gear 29 and the tightness of the sprocket chain can be adjusted.

A shifting lever 36 is pivoted by a suitable screw on the bracket- 19. This lever has a pin or projection 37 which engages into a groove 38 formed in the hub 24. A light loop of wire 39 is adjustably secured to the lever 36 by a screw 40. The end of this loop carries a block and friction pad 41 which, when the lever is in the position shown in Fig. 1, comes in position to engage the side of the sprocket gear 29. A cam lever 42 is pivoted on a suitable screw 43 secured in the foot of the bracket 19. This cam lever has two notches 420-421 which are engage by a roller 44 journaled on a screw 45 secured in the end of the shifting lever 36. The journal 46 or pivot of the take-up spool D is fitted into a hole bored centrally in the pinion 21, a small spiral spring being inserted in the hole to keep the take-up spool in its left-hand position.

A plate 48 is secured by screws to the inside of the cheek A. A screw stud 49 is secured in this plate and running on the same is an intermediategear 50 which is in continuous mesh with the pinion 21. Journaled on the stud screw 49 is an arm 51 secured in the end of which is a screw stud 52 on which is loosely mounted a pinion 53. The screw stud 52 is extended through the arm 51 and is engaged by a projection 422 extending out from the cam lever 42. A spiral spring 54 is arranged between the screw stud 52 and a screw 55 secured in the cheek. Agear 56 is arranged on the take-up spool D. r

- The pinion 53 is in constant engagement with the'intermediategear 50 and is made wide-faced so that when in its lower position, as shown in Fig. 5, it will engage with V ment with the gear 56 and the take-up spool D will be free to run backwardJ The operation'is as follows,Power is applied from a suitable motor by any suit able connection such as the usual sprocket pinion, chain and gear, to operate the power shaft 23. The shifting lever 36 is connected by the usual link-work to the controlling lever of the instrument. Then the shifting lever 36 is in the position shown in Fig. 1, the hub 24 will be in the left-hand position so that its clutch tooth 25 will engage with the clutch tooth 26 on the collar 22, whereby power will be transmitted from the shaft 23 to the pinion 21. When the parts are in this position, the roller 44 will be in the notch 420 of the gear lever 42, which will bring the pinion 53 to the position shown in Fig. 5, wherebypower will be transmitted from pinion 21, gear 50, pinion 53 to the gear 56 on the take-up spool, whereby the latter will be rotated at a slow speed in a directionto draw the music sheet forward over the tracker. As this action takesplace, the music spool B will be rotated by the notesheet and by means of the sprocket pinion 14, and sprocket chain 32, the sprocket gear 29 will be slowly rotated. When the parts are in this position, the friction pad or block 41 will engage the side of the sprocket gear 29 and thus will hold back slightly on the music spool so that there will be some tension put on the music sheet as the same is drawn over the tracker,

The operation is reversed when the shifting lever 36 is thrown tothe position shown in dotted lines in Fig. 1 and to the position shown in Fig. 2. When the lever'is-thrown to this position, the hub '24 is moved to the right so that the clutch tooth 27 will engage the clutch t0oth'28 on the sprocket-gear 29 and so that the clutch teeth 25 and 26 will be disengaged. By this adjustment, the

side of the sprocketgear in the claims.

power will be taken through the sprocket gear 29, sprocket chain 32, sprocket pinion 14, and the music spool will be quickly rotated in a reverse direction to rewind the music sheetJ When this action takes place, the friction pad 41 is disengaged from the Also when this action takes place, the roller'44 on the shifting lever 36'willcome into the notch 421 of the cam lever 42. This will raise the pinion 53 clear or out of mesh with the gear 56 on the take-up spool. fhis will allow'the music spool to turn backward so that the music sheet can'be drawn therefrom. When the parts are in this position, it will be noted that the pinion 21, intermediate 50, and pin-' ion 53 are not operated, whereby there is very little friction interposed to the rewinding of the music sheet. V

The notches 420 and 421 insure the correct action-of'the shifting lever, the spring 54 acting to pull the notched end of the cam lever 42 upwardly so that the shifting lever 36 will have to assume one or the other of its two positions. By throwing the pinion 53 sidewise or down and up into and out of mesh with the gear 56, a very positive and accurate gear shift is obtained. By the use of the double clutch device, consisting of the hub 24 and its two clutch teeth, the gearing above described is thrown out of operation for rewinding. The notched cam lever, as previously described, insures the accurate positioning of the shifting lever in either one of its two positions. The tension spring 54 operates to hold the pinion 53 accurately in mesh with the gear 56 when the parts are in the position shown in Fig. 5. 7

The spring and friction block 41, coiiperating with the side of the sprocket gear 29, forms an efficient braking mechanism for the purpose set forth. 7

By the mechanism described, the func-' tions necessary to a gearing of this kind are accurately performed.
